With the help of scallywags Deek, Smeek (Jim Boles), and Izralim, Captain Alonzo P. Tucker returns to search for the lost treasure of Beelibones. Having discovered alost-in-space-treasure-of-the-lost-planet doodlebug (i.e. a talking, disembodied head), Dr. Smith is kidnapped by Tucker’s motley crew and forced to cooperate with them.

“Treasure of the Lost Planet” is an underwhelming sequel to “The Sky Pirate.” Specifically, Carey Wilber’s narrative fails to achieve a sufficient balance of humor, action, and adventure—all essential factors in a pirate-themed episode for children.



The comedic nature of Captain Tucker serves to complement the campy, lighthearted tone adopted by many second season episodes of Lost in Space—in contrast to lost-in-space-treasure-of-the-lost-planetTucker’s presence in “The Sky Pirate,” which instead clashes with the dark and serious subject matter whereby much of season one is defined.

Also worth commending, Will and Tucker share a natural chemistry with each other this time around—another improvement over “The Sky Pirate,” and one that strengthens the credibility of a most unlikely friendship.



lost-in-space-treasure-of-the-planetA plodding effort, “Treasure of the Lost Planet” lacks a compelling, swiftly-paced execution to make riveting the central conflict of Wilber’s aforementioned narrative.

Additionally problematic is that none of the characters in Tucker’s gang possess interesting (or even somewhat human) qualities with which the average person can relate. Therefore, the majority of viewers—including those from a young age group—may struggle to invest in the treasure hunt whereon all four men embark.



Never trust a pirate.


Concluding Comments

Though mildly amusing on occasion, “Treasure of the Lost Planet” would best be avoided by all but the most enthusiastic fans of Lost in Space. Any interactions between Will and Tucker should, however, be praised for showcasing the talents of Billy Mumy and Albert Salmi, respectively.


Overall Quality: 3/10

  1. This is my number twenty-one ranked episode for the classic down home, cozy and fun, colored mid season..my second favorite season of the series, despite its much maligned and unwarranted status.. :-]

  2. Captain Tucker is back! I think you either love the captain or you hate him. As for me, I love him. This one, of course, cannot compare to the first B&W warm classic, but I love this story just fine. It does not stand out too much. It is just sort of ‘there,’ but it is just fine. I do like the story and I do like the captain’s motley crew.

    The old 1998 trivia book Season Two rankings had this episode dead last on the year. Yeah right. As for me, look above for my official ranking. Captain Tucker, although maybe not your classic ‘science fiction’ character, is back..and the lovable character deserved it..
